The pixbufcache
class generates the proper
post-install and post-remove (postinst/postrm) scriptlets for packages
that install pixbuf loaders, which are used with
gdk-pixbuf
.
These scriptlets call update_pixbuf_cache
to add the pixbuf loaders to the cache.
Since the cache files are architecture-specific,
update_pixbuf_cache
is run using QEMU if the
postinst scriptlets need to be run on the build host during image
creation.
If the pixbuf loaders being installed are in packages other
than the recipe's main package, set
PIXBUF_PACKAGES
to specify the packages containing the loaders.
